Organic soil nutrition
Exploring neem-derived organic materials as part of fertilizer systems designed to support soil organic matter, nutrient availability and longer-term soil fertility.
RESEARCH & INNOVATION
Researching neem. Building practical products.
Rijona explores how neem can solve practical problems across agriculture and personal care — from improving nutrient efficiency and soil health to developing functional everyday products.
RIJONA R&D
From neem seed to finished solution.
WHAT DRIVES THE WORK
We do not start with a product. We start with a problem.
01
Understand the need
We begin with the challenge — nutrient loss, poor soil condition, crop protection, resource waste or a personal-care need.
02
Find where neem adds value
We examine how neem oil, neem cake and other neem-derived materials can contribute to a practical solution.
03
Develop, test and improve
Formulations move through testing, observation, user feedback and refinement before the next stage of development.
OUR RESEARCH AREAS
One plant. Multiple applications.
Nitrogen retention
Developing neem-coated urea to reduce nitrogen losses, support more gradual nitrogen availability and improve the efficiency of conventional fertilizer use.
Plant & root nutrition
Developing neem-and-phosphate formulations focused on phosphorus availability, root establishment and the wider condition of the soil.
Botanical pest management
Investigating neem and other plant-derived materials for crop-protection formulations that can form part of integrated pest-management approaches.
Neem-based skin care
Developing creams, lotions, oils and other personal-care formats around neem's recognised antioxidant, anti-inflammatory and antimicrobial properties.
Neem value addition
Improving how neem seed, oil and cake are processed so that more value can be created from one local biological resource across multiple product categories.
FROM RESOURCE TO PRODUCT
Building more value from neem.
Neem is often treated as a single-purpose plant. Rijona looks at it differently. The oil can support crop-protection and personal-care applications, while the remaining neem cake can be used in soil and fertilizer development.
That creates a connected research model in which one raw material can contribute to several products instead of generating unnecessary waste.
This is the thinking behind both Nourishnest and AgriNeemix: different applications, but a common research foundation centred on neem.
EARLY RIJONA TESTING
Evidence is part of the product-development process.
50%
Up to lower nitrogen losses
Rijona testing of our neem-coated urea recorded reductions in nitrogen losses of up to 50%.
30%
Up to improvement in crop yield
The same product-development testing recorded crop yield improvements of up to 30% under the tested conditions.
Field
Farmer-informed development
Products are tested alongside practical farmer engagement so that feedback can inform further development and refinement.
HOW WE DEVELOP
A continuous learning process.
01
Identify
Start with a real problem in agriculture, personal care or resource use.
02
Formulate
Develop a neem-based product concept around the problem being addressed.
03
Test
Evaluate product behaviour through practical testing, field use and observation.
04
Improve
Use findings and user feedback to refine the product and guide the next stage of development.
